Jeremy Michael London and his twin brother Jason London were born in San Diego, California, and were raised in Oklahoma and DeSoto, Texas. Jeremy was the first of the two to start auditioning, but it was Jason who nabbed the first role in the movie The Man in the Moon (1991). Jason also got a role in the dramatic series I'll Fly Away (1991), starring alongside Sam Waterston, but had to turn it down because of another job. So Jeremy auditioned for the role and got it instead. Jeremy has blue-green eyes and brown hair.
